I picked up a Lull just to try one out, but it has not wowed me. I currently stick with the Roscoe and the Laklands. So price point and no "Wow" factor to pull those sales away from a Fender or Music Man. I mean it's light, but so are the rest of mine.
I don't think of a Lull as a "wow" kind of bass - and I think I know what you mean by this...there have been some instruments, e.g. a fancy Roscoe or MTD, that I've picked up and had that sort of reaction. But for strapping on and rocking on a stage...often with a pick... for hours, these kinds of basses never worked for me too well.
As you know, the Lull is a Fender-style instrument with a higher quality build. Usually no fancy tops or unique designs...just a really well-made tool to rock the house. What sets it apart to me are its dimensions and killer action.
Sadowsky and Lakland make a great product too, but I prefer Lull dimensions and action. Oh yeah, and as you mention, they are light weight usually, which is an absolute must for me these days.
